Advanced Radio Resource Management for IMT-Advanced in WINNER+ (II)

Two main draft standards were submitted in October 2009 as candidate technologies for IMT-Advanced, namely IEEE 802.16m and 3GPP LTE-Advanced. However, several details on their functionalities are still open and the research community is racing towards the complete definition of the revolutionary next fourth generation mobile, 4G. In this framework the European Celtic project WINNER+ is bridging together experts from industry, academia and government all around Europe to devise these 4G technologies. This paper presents the second part of innovative concepts for advanced Radio Resource Management that has been identified by the Innovation Group of WINNER+ for potential inclusion in IMT-Advanced. These concepts consist of promising innovative techniques that are ready to be included in current OFDMA-based cellular systems to enhance system performance. A brief description of each technique together with the relevant state of the art is provided.
